This study examines whether the spacing of a single unreinforced retrieval trial relative to extinction learning allows for “rewriting” the original disgust association, thereby preventing the return of disgust using a paradigm that employs disgust-relevant unconditioned stimuli (US). During conditioning, disgusting US were paired with a color square that served as the conditioned stimuli (CS). Participants (n = 54) then returned to the lab 24 hours later and received a “reactivation” intervention which consisted of one unpaired presentation of the CS+. Participants were then randomized to receive extinction trials either 10 min (Group A) or 6 hours (Group B) after reactivation. A third control group (Group C) did not receive the reactivation manipulation before extinction. Participants returned 24 hours later for additional extinction trials and at a 1-month follow-up for disgust reinstatement. Although the paradigm resulted in participants evaluating the CS+ as significantly more unpleasant after being associated with a disgust-relevant US, extinction learning within the reconsolidation window did not influence self-reported reduction or return of disgust. However, there was some evidence suggesting that those who received reactivation (Groups A and B), regardless of timing, evaluated the CS+ as less unpleasant after extinction relative to acquisition, whereas this pattern was not observed among those who did not receive reactivation (Group C). The implications of these findings for anxiety-related disorders in which disgust has been implicated will be discussed.

Background Venus ulcers developed mainly due to reflux of incompetent venous valves in perforating veins. Patients and methods In this randomized controlled trial, 119 patients recruited over two years, with post-phelebtic venous leg ulcers, were randomly assigned into one of two groups: either to receive radiofrequency ablation of markedly incompetent perforators (Group A, n = 62 patients) or to receive conventional compression therapy (Group B, n = 57 patients). Follow-up duration required for ulcer healing continued for 24 months post randomization. Results Statistically significant shorter time to healing (ulcer complete healing or satisfactory clinical improvement) between both groups (56 patients, 90.3% of cases in Group A versus 44 patients 77.2% of cases in Group B) over the follow-up period of 24 months was attained ( p  = 0.001). Also, significantly different ulcer recurrence was recorded between both groups, 8 patients (12.9%) in Group A versus 19 patients (33.3%) in Group B ( p = 0.004). Conclusion In absence of deep venous obstruction, the monopolar radiofrequency ablation for incompetent perforators is a feasible and effective method that surpasses the traditional compression protocol for incompetent perforator-induced venous ulcers in terms of time required for healing even in the presence of unresolved deep venous valvular reflux.

Abstract Objective To investigate the impact of microecological preparation combined with modified low-carbon diet on the glucolipid metabolism and cardiovascular complication in obese patients. Methods From August 2017 to July 2020, 66 obese patients were recruited, and administrated with an modified low-carbon diet with (group A) or without (Group B) microecology preparation and a balanced diet in control group (group C) for 6 months. Meanwhile, 20 volunteers administrated with a balanced diet were recruited as the healthy control group (group D). Results After 6-month intervention, obese subjects in group A and B showed significant improvement of body and liver fat mass, reduction of serum lipid levels, intestinal barrier function markers, insulin resistance index (IRI), high blood pressure (HBP) and carotid intima thickness, as compared with subjects in group C. More importantly, subjects in group A had better improvement of vascular endothelial elasticity and intimal thickness than subjects in group B. However, these intervention had no effect on carotid atherosclerotic plaque. Conclusion Administration of microecological preparation combined with modified low-carbon diet had better improvement of intestinal barrier function, glucose and lipid metabolism, and cardiovascular complications than low-carbon diet in obese patients, but the effect of a simple low-carb diet on carotid atherosclerotic plaque need to be further addressed.

AbstractIntroduction:Laryngopharyngeal reflux is increasingly being implicated in several otolaryngological disorders.Aims:To study a potential correlation between pre-operative laryngopharyngeal reflux and wound healing and recovery after tonsillectomy, based on subjective and objective findings.Materials and methods:A prospective, blinded study was undertaken, including 60 patients scheduled for tonsillectomy, divided into two equal groups: a study group (group A) with pre-operative laryngopharyngeal reflux documented using ambulatory 24-hour pH monitoring; and a control group (group B) without laryngopharyngeal reflux.Results:Group A had significantly higher pain scores on the seventh and 14th post-operative days (p = 0.022 and p = 0.000, respectively) and took a significantly longer time to return to normal eating (p = 0.013), compared with group B. Group A also showed significantly slower healing on the seventh and 14th post-operative days, as estimated by assessing the grade of post-operative slough formation (p = 0.016 and p = 0.029, respectively). A significant correlation between the number of pharyngeal reflux episodes and the degree of post-operative slough was also found.Conclusions:Laryngopharyngeal reflux can significantly decrease wound healing following tonsillectomy. Therefore, pre-operative recognition and management of this condition is desirable in order to eliminate its negative post-operative effect.

AIM: To investigate the protective effect of human umbilical cord mesenchymal stem cells (hUCMSCs) modified by the LIF gene on the retinal function of diabetic model rats and preliminarily explore the possible mechanism. METHODS: A stably transfected cell line of hUCMSCs overexpressing leukemia inhibitory factor (LIF) was constructed. Overexpression was verified by fluorescent quantitative polymerase chain reaction (qPCR). Forty-eight adult Sprague-Dawley rats were randomly divided into a normal control group (group A), streptozotocin-induced diabetic control group (group B), diabetic rats at 3mo injected with empty vector-transfected hUCMSCs (group C) or injected with LIF-hUCMSCs (group D). Four weeks after the intravitreal injection, analyses in all groups included retinal function using flash electroretinogram (F-ERG), retinal blood vessel examination of retinal flat mounts perfused with fluorescein isothiocyanate-dextran (FITC-dextran), and retinal structure examination of sections using hematoxylin and eosin staining. Expression levels of adiponectin (APN), high-sensitivity C-reactive protein (hs-CRP), and neurotrophin-4 (NT-4) in each group was detected using immunohistochemistry, PCR, Western blotting, and ELISA, respectively. RESULTS: A stable transgenic cell line of LIF-hUCMSCs was constructed. F-ERG and FITC-dextran examinations revealed no abnormalities of retinal structure and function in group A, severe damage of the retinal blood vessels and function in group B, and improved retinal structure and function in group C and especially group D. qPCR, ELISA, and Western blot analyses revealed progressively higher APN and NT-4 expression levels in groups B, C, and D than in group A. hs-CRP expression was significantly higher in group B than in groups A, C, and D, and was significantly higher in group C than in group D (P<0.05). CONCLUSION: LIF-hUCMSCs protect the retina of diabetic rats by upregulating APN and NT-4 expression and downregulating hs-CRP expression in the retina.

PURPOSE: To evaluate axonal regeneration after end-to-side nerve repair with fibrin glue in rats. METHODS: Forty-five Wistar rats were divided into three groups: group A (n=15), were not submitted to surgery (control group); group B (n=15) were submitted to fibular transection without repair; and group C (n=15), were submitted to fibular transection with end-to-side nerve anastomosis using fibrin glue, in the lateral surface of an intact tibial nerve. The three groups were submitted to walking track (30 and 90 days) and posterior morphometrical analysis (90 days). RESULTS: The functional tests demonstrated that there was no difference in the walking track during the study in group A (p>0.05). The group B had walking pattern impairment in the two tests (p>0.05). The group C had walking pattern impairment in the first test, with important recovery in the second test (p<0.05). The morphometrical assessment revealed significantly higher number of regenerated mielinates axons in group C, compared to group B (p<0.05). CONCLUSION: The end-to-side nerve repair with fibrin glue shows axonal recovery, demonstrated through functional and morphometrical ways in rats.

Background. Weight regain after laparoscopic sleeve gastrectomy (LSG) is nowadays a growing concern. Sleeve dilatation and loss of food restriction is considered the main mechanism. The placement of a silicon ring around the gastric tube seems to give benefits in the short term. We report the results of a randomized study comparing LSG and laparoscopic banded sleeve gastrectomy (LBSG) over a 4-year follow-up. Objectives. To evaluate the efficacy of banded sleeve gastrectomy compared to standard sleeve in the midterm. Methods. Between 01/2014 and 01/2015, we randomly assigned 50 patients to receive one of the two procedures. Patients’ management was exactly the same, apart from the band placement. We analyzed differences in weight loss, operative time, complication rate, and mortality, with a median follow-up of 4 years. Results. Twenty five patients were assigned to receive LSG (Group A) and 25 LBSG (Group B). The mean preoperative BMI (body mass index) was 47.3 ± 6.58 kg/m2 and 45.95 ± 5.85 kg/m2, respectively. There was no significant difference in the operative time. No intraoperative or postoperative complications occurred. At 12-month follow-up, the mean BMI was 29.72 ± 4.40 kg/m2 in Group A and 27.42 ± 4.47 kg/m2 in Group B (p=0.186). After a median follow-up of 4 years, the mean BMI in Group B was significantly lower than Group A (24.10 ± 4.52 kg/m2 vs 28.80 ± 4.62 kg/m2; p=0.00199). Conclusions. LBSG is a safe procedure, with no impact on postoperative complications. The banded sleeve showed a significant greater weight loss in the midterm follow-up. Considering the issue of weight regain observed after LSG, the placement of a perigastric ring during the first procedure may be a strategy to improve the results. This trial is registered with NCT04228185.

Objective: To study the effect and safety of Fenofibrate in uncomplicated hyperbilirubinemia in newborn with 6-month follow-up. Materials and Methods: This is a randomized controlled clinical trial conducted in 60 normal term neonates admitted for uncomplicated hyperbilirubinemia in NICU at Sir T G Hospital, Bhavnagar from January 2012 to December 2012. The data included: age, sex, total serum bilirubin (TSB), weight and duration of phototherapy. All neonates enrolled in the study received phototherapy. They were divided in two groups of 30 each: control group A and group B receiving Fenofibrate (100 mg/kg single dose). There was statistically insignificant difference between the parameters of age, sex, weight and TSB between the two groups at hospitalization. Data was analyzed by using appropriate statistical methods. Results: Mean values for total serum bilirubin in Fenofibrate group B at 24 and 48 hours after admission were significantly lower than those for control group A (p<0.0001,  p=0.0001). There was no significant difference in fall of TSB between 24 and 48 hours. The mean duration of phototherapy in Fenofibrate group (44.8h: 24-72h) was significantly shorter than that in control group (55.2 h: 24‐96 h) (P=0.02). There were no side effects of the drug observed during the study and during 6 months follow up period. Conclusion: Fenofibrate as a single 100 mg/kg dose in healthy full term neonates, is effective and a safe drug (till six-month follow-up) for neonatal hyperbilirubinemia, that can decrease the time needed for phototherapy and hence hospitalization. Effect of a single dose seems to wane after 24 hours.

The effects of three dissolving agents on the accuracy of an electronic apex locator- (EAL-) integrated endodontic handpiece during retreatment procedures were evaluated. The true lengths (TLs) of 56 extracted incisor teeth were determined visually. Twenty teeth were filled with gutta-percha and a resin-based sealer (group A), 20 with gutta-percha and a zinc oxide/eugenol-based sealer (group B), and 16 roots were used as the control group (group C). All roots were prepared to TL. Guttasolv, Resosolv, and Endosolv E were used as the dissolving solutions. Two evaluations of the handpiece were performed: the apical accuracy during the auto reverse function (ARL) and the apex locator function (EL) alone. The ARL function of the handpiece gave acceptable results. There were significant differences between the EL mode measurements and the TL (P<0.05). In these comparisons, Tri Auto ZX EL mode measurements were significantly shorter than those of the TL.

Objective: To study the effect of liposomal curcumin combined with PDGFBB on tendon healing after tendon injury in rats and explore its mechanism. Methods Thirty-six rats were randomly divided into four groups: healthy control group (group A), liposomal curcumin group (group B), PDGF-BB group (group C) and combined application group (group D). The rats in each group were divided into groups according to the experimental group. At the 4th and 8th weeks after operation, the general morphology, histomorphology, biomechanics and other aspects of rat tendon were detected and statistically analyzed. Results: The degree of tendon adhesion in group B and D was significantly less than that in group A and C, and the difference was statistically significant. The biomechanical test showed that the tendons in group C and D had higher strength and could withstand greater stress than those in group A and B. Conclusion: Liposome curcumin combined with PDGF-BB can significantly reduce the degree of adhesion after tendon injury, increase the strength of tendon healing, and significantly promote tendon healing.
